This standard specifies the geometric accuracy test items, tolerances and test methods for general-purpose mechanical dividing heads for machine tools. This standard applies to the accuracy test of dividing heads. It does not apply to the operation test of dividing heads, which is generally carried out before the accuracy test.

This standard equivalently adopts the international standard IS05734-1S86 machine tool dividing head inspection case change inspection, and abolishes the basic international standard 2554-4 in terms of technical content, resulting in some continuous changes, and omitting the provisions of GB/T1.11993, etc. The design rules of this standard can be simplified by adopting the national standard S5734-186. The British standard is not included in the data. Compared with the previous version, the addition of "the same rail joint auxiliary inspection head" and "the standard rail line to the reference type Bo side of the inspection must be implemented. This standard replaces GB2554-84 from the date of implementation. This standard is proposed by the Ministry of Machinery Industry of Shandong Province.
This standard is under the jurisdiction of the State Machine Tool Accessories Research Institute. The responsible drafting of this standard is: Taiwan Machine Tool Accessories Research Institute: The drafting of this standard is: Yanji Machine Tool Accessories Factory, Wuhan Machine Tool Accessories Factory. This standard was issued for the first time in 1573, and will be revised for the second time in 1981, and will be revised for the second time in 1381. c8/T2554.1—1998www.bzxz.net
ISO Foreword
ISO is a worldwide standard organization. The preparation of international standards is usually carried out by ISO technical committees, which represent the interests of all standard-setting bodies concerned with the standard being prepared. 15 relevant international organizations, governmental and non-governmental organizations, help plan this work.
The draft standard shall be published after the decision of the main S) Council. According to the 1 effective) execution procedure, 75% of the testers must pass the test before the standard is released. The international standard IS)5724 was developed by the ISO/TCS5\Machine Tool Technical Committee". This is the second edition, which replaced the first edition (1S)5734-1978). Geometric inspection G1, (F5 and G6 items have been revised. Users need to be aware that all international standards will be revised and the referenced standards, unless otherwise specified, refer to the latest versions. Scope

This standard is generally used to define the inspection items and supplementary inspection methods of the dividing head for machine tools (hereinafter referred to as the dividing head):
This standard is used for the initial inspection of the dividing head: It is not suitable for the operation inspection of the dividing head. The operation inspection of the dividing head is generally carried out before the accuracy inspection:
2 Reference standard
Next The provisions contained in the following standards are cited in this standard and constitute the text of this standard. The versions shown are valid at the time of publication of the standard: All standards will be referenced. The parties who use this standard should consider the latest version of the following standards: J/T2570-182 Precision inspection rules for metalworking machine tools 3 General requirements
3.1 The precision inspection method of this standard should be in accordance with the relevant provisions of 113/1267C. 3.2 The precision inspection items listed in this standard are listed in the order of , it is not necessary to conduct the actual inspection. During the inspection, the inspection can be carried out according to the convenience of assembly and disassembly of the mold and the inspection can be carried out in any order. 3.3 The parts specified in this standard can be selected for inspection according to the agreement. 3.4 If the actual measured length is different from the measured length specified in this standard, the difference can be converted according to the provisions of 2.3.1.1 of JB/T2570:1932. If the conversion result is less than c.510mm, it shall be calculated as 0.c13mm. 4 Geometric accuracy inspection (See table:)
